WILLIAM GENT, OF ROCKFORD, ILLINOIS. Y

CARRIAGE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 360,874, dated April12, 1887.

Application filed June 2S, 1886. Serial No. 206.546.

To all whom it may concern:

Be it known that I, WILLIAM GENT, a citizen of the United States,residing at Rockford, in the county of W'innebago and State of Illinois,have invented certain new and useful Improvements in AdjustableCarriage- Wrenches, of which the following is aspeoification.

My invention relates to improvements in that class of wrenches commonlyknown as the carriage-wrench. 7

My invention consists Iin producing a wrench having a pair of jawshinged together by means of a hinge-joint, said jaws being capable ofadjustment by means of a threaded handle passed through them, and alsoprovided with a revolving `handle at the hinge-joint end thereof.

Referring to the accompanying drawings, which form apart of thisspecification, Figure l represents a side view of my improved wrench,with a portion thereof removed to show interior construction. Fig. 2represents an isometrical View of a portion of the same.

Similar letters of reference indicate corresponding parts throughout thetwo views.

j A A represent jaws joined together by means of a hinge-joint, A2, andprovided at their free ends with semi-rectangular mortises A3, foradmitting and grasping the rectangular boss of an axle-nut.

B represents webs for strengthening the wrench-jaws A A.

B represents spurs for retaining the helical actuating-spring B2 inposition.

C C represent tubular openings through the jaws A A', the latter beingprovided with an internal screw.

(No model.)

D represents a handle,- having -a tubular opening through thelongitudinal center there- 4o of.

D represents a rotating axle passed through the longitudinal center ofthe handle D.

E represents a regulating-screw, for regulating the jaws A A.

E represents a handle, of good lengthand considerable weight, foroperating the regulating-screw E, and also for revolving the Wrench.

This wrench can be manufactured most ad- 5o vantageously and cheaply ofmalleable or cast iron. I prefer to use round bar-iron for making theparts D E.

`To use the wrench most effectually, pass the Open jaws thereof over theboss of the nut to be removed. Tighten the screw E until the boss isheld with a firm grip. Grasp the handleD with one hand, and with theother press the handle E backward until the nut starts from its axle.Then give the handle a vigorous toss, retaining the hold upon the handleD, and it will continue to revolve in a plane parallel to thecarriagewheel until the axlenut is removed. A reverse mot-ion of thehandle E will Obviously return the axle-nut to its former position.

I claim- The combination, with the jaw A, of the threaded jaw A', thetubular handle D, rotating axle D', screw E, and handle E', substan- 73tially as described, and for the purpose specified.

TILLIAM GENT.
